Definitions

  • the present invention relates to a device to establish an electric contact between the metallic shielding braid of a cable and the metallic mass of a cubicle inside of which electronic or telecommunication equipment are housed, in the penetration point of the cable through the wall of the cubicle.
  • the portion of the shielded cable contained inside the cubicle may constitute a way of access for electromagnetic disturbances due to the currents circulating in the metallic shielding braid of the cable.
  • the device is set-up by at least two deformable metallic braid clamping bodies substantially shaped as a cylindric sector and preferably by the number of two; the sectors provide contact for the shielding braid of the cable passing through the hole of the wall and the wall itself of the cubicle.
  • Each sector (or halfbush) is set-up by a metallic body provided with alternating longitudinal partial cuts, conferring to each element, and therefore to the whole bush, a radial elasticity; each sector (or halfbush) is also provided with radial projections suitable to set-up a circular portion of support flange on the face (typically on the external one) of the metallic wall of the cubicle adjacent to the passage hole of the cable.
  • the top edges of the sectors (or of the two halfbushes) have a conical shape such to realize a trunkconical surface of the whole contact bush.
  • the opposed radial coupling faces of the different sectors are provided with a spacer relief in the proximity of their bottom end; the bottom end is placed inside the cubicle, in the other side of the drilled wall opposed to the top extremity (external to the cubicle) with said conical surface.
  • a coupling or cylindric metal crampling ring is previously inserted along the cable (that have been passed through the hole) and is forcedly pushed over the external extremities of the sectors (or of both halfbushes).
  • the cylindric metal clamping ring is provided with an internal trunkconical surface suitable to press against the trunkconical edge of the contact bush, pushing inside the edges of the sectors (or of both halfbushes) and forcing contact on the metallic shielding braid of the cable.
  • the internal cylindric face of the metal ring is provided with longitudinal ribs extending over it's bottom edge; the bottom edge gets inserted in the separation space between the opposed radial coupling faces, (spaced by said reliefs), of the sectors (or both halfbushes), setting up the contact bush.
  • the ribs Contemporaneously to the inside-press action (carried out by the trunkconical internal surfaces of the metal ring on the conic extremities of the sectors or both halfbushes), the ribs (or longitudinal noses) extend over the bottom edge of the bush, interfering with the relief present on the radial coupling faces of the sectors (or both halfbushes); the opposed bottom extremities of the sectors, are in this way pressed against the metallic wall of the passage hole of the cable (outside-press action). Suitable reliefs or radial teeth (which may be present on the extremities of the sectors or divaricated halfbushes) are pressed under the edge of the passage hole, preventing the tearing of the contact and fixing the cable.
  • the metal clamping ring (or sleeve) is provided with a longitudinal cut, suitable to give radial elasticity to the ring.
  • Figures 1, 2, 3 show the installation steps of the contact and anchorage device for a shielded cable 1 passing through an input hole 2 of a metallic wall 3 of a shielded cubicle or room inside of which equipment may be housed being sensible to electromagnetic disturbances.
  • the shielded cable 1 must be free of the isolating sheathing the passage part through the hole 2 in order to uncover the metallic shielding braid 4. Before passing the cable through the hole 2 it is necessary to put the blocking sleeve or metal ring 5 on the cable.
  • the cable is therefore positioned and two metallic halfbushes, 6a and 6b, respectively, are put into the same hole 2 of the metallic wall 3 of the cubicle.
  • Each one of the metallic contact halfbushes may be realized by starting from a metal section (which may be incised by shearing and then cut and shaped like a halfbush) or by mechanical toding.
  • the material used for the two halfbushes 6a and 6b may be copper, nickelled copper, stainless steel or other suitable metallic material.
  • the two halfbushes 6a and 6b are essentially provided with longitudinal alternating cuts 7 and 8 suitable to give radial elasticity (by stressing the "particularities" of the link between the subsectors in which each halfbush turns out to be subdivided) and of radial projections 9 suitable to set-up circular portions of a support flange on the face of the wall 3, adjacent to the passage hole 2, as shown in Fig. 2.
  • the radial "coupling" faces 10 and 11 are provided (in correspondence of the passage area of the extremities of the bushes put through hole 2) with spacer relieves 12 (see also Fig. 5) suitable to maintain a certain distance between the opposed radial faces 10 and 11 of both halfbushes, when these are put inside the hole 2 around the cable 1.
  • top ends of the halfbushes are provided with a conic surface 13 in order to set-up an essentially trunkconical extremity of the bush composed by the two sectors (halfbushes) 6a and 6b.
  • the blocking sleeve or metal ring 5 (which may be made of metallic material similar to the one used to make the halfbushes 6a and 6b, or also of different material) is preferably provided with a longitudinal cut 14 suitable to give it a radial elasticity.
  • the metal clamping ring is moreover provided with internal longitudinal ribs 15 (in the same number of the sectors 6a and 6b which set-up the cylindric contact bush), two in the illustrated case.
  • the snugs 15a and the corresponding longitudinal ribs 15, are sliding between the opposed radial coupling faces of the different sectors 6a and 6b, setting up the contact bush, (which are maintained at a distance by the reliefs 12).
  • the clamping metal ring 5 is pushed over the contact bush, until it's shoulder touches the radial projections 9.
  • the internal trunkconical surface 17 (see Fig. 4) of the clamping ring 5 abuts and interferes with the conical external surfaces 13 of the halfbushes 6a and 6b, pushing them inside and against the metallic braid 4 of the shielded cable (in order to realize a good electric contact with this one).
  • the snugs 15a interfering with the spacer reliefs 12 (on the radial coupling faces of the halfbushes 6a and 6b) divaricate the bottom part of the halfbushes 6a and 6b, pushing the extremities against the walls of the hole (establishing therefore a contact with the metallic mass of the wall 3 of the cubicle).
  • Fig. 4 is an axonometric view, partially in cross section, of the clamping metal ring 5, where it is possible to see the internal trunkconial surface 17, suitable to abut on the conical surfaces 13 of the halfbushes pushing the respective extremities against the metallic braid of the shielded cable, as well as the shape of the internal longitudinal ribs 15, extended over the bottom edge of the metal ring, in order to set-up snugs (or extensions) 15a.
  • Fig. 5 is a magnified view of one contact sector or halfbush 6a where it is easier to identify the already described particularities.
  • One of such variations may be, for instance, inherent to the presence of release stop means (not shown) of the blocking metal ring 5, against said halfbushes 6a and 6b, for example under the form of projections foreseen on said longitudinal ribs that enter seats provided for on the opposite faces 10 and 11 of said two halfbushes 6a and 6b.
